摘要： This invention is based upon the discovery that cyclized polyisoprene polymers can be incorporated into tire tread compounds to improve traction, treadwear, and resistance to tear. It is further based upon the discovery that cyclized polyisoprene polymers can be blended with halobutyl rubber and/or natural rubber and can be utilized in tire innerliner formulations. The present invention more specifically discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, wherein said tread is adapted to be ground-contacting, and wherein said tread is comprised of a sulfur cured rubber composition which is comprised of about 5 phr to about 50 phr of cyclized polyisoprene and about 50 phr to about 95 phr of at least one other rubbery polymer. The present invention further discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, an innerliner, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, wherein said innerliner is comprised of a sulfur cured rubber composition which is comprised of about 5 phr to about 50 phr of cyclized polyisoprene and about 50 phr to about 95 phr of at least one other rubbery polymer selected from the group consisting of natural rubber and halobutyl rubber.

摘要： The present invention relates to a process for the preparation of epoxidized synthetic cis-1,4-polyisoprene. The process involves reacting the synthetic cis-1,4-polyisoprene in a C5-C7 aliphatic hydrocarbon with tertiary butyl hydroperoxide in the presence of a molybdenum catalyst at a reaction temperature ranging from about 20 DEG C to about 100 DEG C. The molybdenum catalyst is prepared by reacting together under a N2 atmosphere molybdenum pentachloride with a carboxylic acid of the formula: CH3(CH2)nCOOH wherein n is an integer ranging from 8 to 28. The molar ratio of molybdenum pentachloride to the carboxylic acid ranges from about 1:1 to 1:3.
